IPC: H04L12/24
Filed: 2018-09-18
Abstract: Embodiments of the present invention provide a data reporting method and system. The method comprises: step 1, a main network node generates a data uploading token; step 2, each network node which is about to upload data determines whether the network node has data uploading qualifications; and step 3, a network node having the data uploading qualifications contends for the data uploading token, and the network node that acquires the data uploading token by means of contention executes a data uploading operation. According to the method and system, when a fault occurs to a server of a network node, data uploading can be automatically switched to a server of another network node without manual intervention, so the data uploading processing time is reduced, and a data timeliness demand is ensured.
